Using pointers to implement your own vector ADT.

In this assignment, you are going to implement your own version of vectors as an ADT to manage a collection of doubles using dynamic arrays. (Note that vector is implemented as a template, but you are only required to implement it as a class.) Specifically, your Vector_double ADT should include the following member functions:

a default constructor.

the "Big-3": destructor, copy constructor and overloaded assignment operator.

the "capacity" function: Returns the maximum number of doubles that your vector ADT could store.

the "empty" function: Tests if the vector container is empty.

the "insert" function: Inserts an element into the vector at a specified position.

the "pop_back" function: Deletes the element at the end of the vector.

the "push_back" function": Adds an element to the end of the vector.

the "resize" function: Specifies a new size for a vector. The new size can be smaller or larger than the old size.

the "shrink_to_fit" function: Discards excess capacity.

the "size" function" Returns the number of elements stored in the vector.

the overloaded output operator (<<) to print out the elements in a vector.
